'engine includes generally a stationary shell within which a' vcutting core or plug is rotatably mounted. The vcutting-knives vof this plug Wear down after some time, and this type of engine is now provided with adjusting mechanism by whichI the plug may be given an endwise or longitudinal movement .relatively to the shell'to' adjust the cuttingsurface of the plug to the. shell, this relative` adjustment ycompensating for thewear of the plug-knives. It has been proposed lto drive this cutting cdre or plug directly from an electric motor, the shaft `of the motor 'and' plug-shaft being arranged in substantially' axial alinement and coupled together, several important advantages resultingffrom suchl arrangement. It hasI also beenfproposed to mova ly`mount the electricmotor, so that the electric`-motor can`be moved with thev core or plug as the latter is moved by the ad-`, justing mechanism. A\ very considerable ,i

strain is thrownA on'the parts of the-mechanism by'this inovement of the motor, and asI now constructed this strain is borne by` the.

coupling member yor clutch connectin l the motor and the plu -shaft and by the a just-l ing mechanism. have discovered that thel proper Workin of the ad'usting mechanism may be insure and the life of the clutch or f coupling prolonged by relieving the coupling 1 and theadjusting mechanism of this .strain by dproviding means independent of theplug an its shaft for adjusting or moving lthe motorendwise as the plug shell, an embodiment of such means being shown in the accompanying drawings, in which- A 4Figure 1 is a side elevation of a paper-rem'ng engine, 'showing the improvement, cershaft 7, journaled in andy its shaft are4 moved orv adjusted endwise relatively to the 5o tain partsA being brokenl away. Fig. 2 is a partial end view of the driving-motor and connections looking in the-'direction of arrow 2 in Fig. i.

bodiment of` the invention, 1 indicatesv av base, which base may be of any usual or desired construction, but which is preferabl so constructed as to' support both the refining-A engine 2 and its driving-motor 3, such construction being convenient. The reiiningengine shown is of the Jordan type and com-A prises an uter stationary-shell 4, su ported 1n any `suitable manner, as by stan ards 5, rising from the base 1, and a cuttin core or plug 6, mounted to rotate `within t e shell. l

his cutting core or plug 6 is mounted on a carin s8 onstandards l9, rising from the basel 1'.

Fig. 3 is an end view, looking in` 'the direction-of arrow 3 in Fi 1', of certain he plug and thev plu -shaft are held normally against endwise or ongitudinal movement lrelatively to the shell 6. As the machine is used, however,

'the knives of theI core or plug Wear down,

andan adjustment of the corerelatively to the. shellis necessary in orderthat the knives onthe cutting-surface of the core or plug may roperl ,operate with the shell in refiny.85 ing t e .'stoc Means are provided, therefore, for both normally holding the plug and plug-shaft against endwise or longitudinal movement re atively 'to the shell vand for givin suchmovement to the plug andits s haft` 're atively tothe shell to effect .this adjustl.

ment, which means include a wheel 4and screw device, such as shown at v10.

The plug-shaft 7 and the plug 6` are driven by a'n electric motor', suchv a motor being shown at`3-, This driving-motor is supported so as to be movable endwise or longitudinally relatively Vto the base 1 and is mounted on the base in any suitable manner to afford such movement. In the construction shown that part of .the base which supports the inotor is provided with projections or raised portions 1'1, one of these raised portions being provided on :each side of the base 1. These raised portions extend upwardly above the plane ofk the'base proper and form tracks' on which the motor is movably supported. The v.motor is slidably retained on these tracks by plates 12, suitably secured to the Itracks, these plates being en aged by flanges 13 on the motor-frame 14. he motor has a 4 shaftl` -15 ri 'dly secured on the motor-arma- 'ture 16,'

y by the adjusting mechanismthroughthe mechanism for the latter.

` endwise by the screw-shaft ing mechanism the motor .which shaft extends t ,plug-shaft and the coupling member connecting the motor-shaft and the plug-shaft the strain of the movement will come on the coupling, plugshaft, and the adjusting The means provided by the present invention for so moving the motor, and thus relieving the coupling member, plug-shaft, and the adjusting mechanism for the latter of this strain, will now be described. These means may be varied, vbutfwill include an adjusting device acting directly on the frame of the motor and coperating with the adjusting mechanism for the core, so that the movement given the motor by this device will be equal to that given the plug bythe adjusting mechanism.

In the specific embodiment of the invention shown there `is rovided a shaft 18, lie length of the machine and is suitably supported in bearings 19 on, the base 1. This shaft has a threaded end 20, which works in a nut 21, suitably secured to the motor-frame 14, preferably, centrally on its lowermost portion, as shown. The other end of this shaft 18 carries a gear .22, which gear meshes with a gear 23; This gear 23 is an intermediate gear and is sup- )ported in any suitable manner, as by a short shaft 24, mounted in a bracket'25, secured on the standard 9. This intermediate ear meshes'with avgear'2`6, which is mounte on thescrew-shaft 27 of 'theA adjusting device 10. By this construction when'the plu is moved 27 of t e adjustis also given an endwisemovement by the with its connections act directly on the motorframe, thus relieving the coupling of strain. ln order that the movement given the motorby the shaft 17 shall be equal to the movement given the plug by the adjusting mechanism, the screw-shaft 27 and the siaft 18 are provided with lthreads of equal pitch and the gears 22 and 26 made equal gears. W ith this construction the motor and the plug are moved endwise at the same time and the same distance.

W hat is claimed isl. ln a reiining-engine, the combination with a stationary shell, of a cutting core or plug rotatably mounted Within the shell, a plug-shaft on which the plug is supported, adjusting mechanism fer adjusting the plug shaft 18, which and its shaft endwise relatively to the shell,
